nit: Is it really necessary to add this precondition?  Won't _open_osfhandle
simply fail when passed a invalid handle value?

nit: This function should also have the AssertIOAllowed() check.

Good question. It does fail and takes entire process with it.

In Debug it looks like

f:\dd\vctools\crt_bld\self_x86\crt\src\fdopen.c(55) : Assertion failed: (filedes
>= 0 && (unsigned)filedes < (unsigned)_nhandle)

While the above is about _fdopen and not _open_osfhandle, I prefer not to mess
with surprising (to me) Windows semantics here.
I removed one from POSIX version so I'm not adding one here for consistency.

+    return NULL;
+  int fd = _open_osfhandle(reinterpret_cast<intptr_t>(file), 0);
+  if (fd < 0)
+    return NULL;
+  return _fdopen(fd, mode);
+}

 bool ClosePlatformFile(PlatformFile file) {
   base::ThreadRestrictions::AssertIOAllowed();
   return (CloseHandle(file) != 0);
